Everton manager David Moyes believes his team need to win their remaining five matches if a Europa League slot is to remain a possibility.
It would be a remarkable achievement given the way they stumbled through the opening part of the campaign when a number of key personnel were injured.
Since the turn of the year Everton have been one of the form sides, picking up 28 points from a possible 42.
That string of good results has seen them move to eighth place in the table, four points behind Wednesday's opponents Aston Villa, who also have a match in hand.
Asked if it was a must-win, Moyes said: 'It probably is. We have to win our games if we are going to make Europe.
'We have always been coming from behind. We had a poor start, the hard part was having three or four serious injuries, and we've been playing catch up. We have done a pretty good job.
'We still have a chance of a European spot but we need to overhaul Aston Villa. It is important and we would like to be there.
'We will do everything we can. We might need other people to help us out but if we don't do our job, it does not matter.
'The players are making a decent fist of it and have done well to get us into this position.'
